-Major case of collusive bidding.
Collusion in bidding is a cancer in bidding activities, which has caused great damage to the fairness and justice of bidding! Collusion bidding is hidden and difficult to identify and investigate, which is one of the reasons why collusion bidding is repeatedly prohibited.
After the public bidding of a civil engineering project, the highest bid price was 450 million yuan, and six companies, A, B, D, H, Q and W * * *, participated in the bidding. After bid evaluation, the winning bidder A is determined, and the winning amount of this project is only lower than the highest bid price 1 10,000 yuan. After signing the contract with the tenderer, the winning bidder A will enter the site for construction preparation. During this period, I received the relevant information about the complaints about the suspected bidding project from the Provincial Commission for Discipline Inspection.
We checked the document attributes (including document creation time, author, computer name, last save time and other parameters) of all electronic tenders of this project, and found that all five companies except Company B created business documents at the same time. Specifically, two bidders' public information, two engineering unit price calculation tables, five bidders' expense tables for producing concrete mixture ratio materials, five bidders' budget price summary tables for purchasing main materials, and four bidders' total bid price are consistent.
After checking the tender document quotation, unit price calculation table, unit price of bill of quantities, data composition, format, personnel organization and construction scheme, the following problems are found:
1. Of the six units that entered the bid evaluation scope, except Company B, the other five units are unusually similar or identical in table body format, space symbol number, material use, mechanical machine-shift charging, etc.
2. Except for Company B, the other five units of the six units that entered the bid evaluation scope are unusually close in the budget prices of main materials and materials such as water, electricity, sand and gravel, and some of them are the same;
3. Among the six units that entered the bid evaluation scope, except Company B, the other five units are unusually close to or even the same as the project unit price calculation table;
4. Among the six units that entered the bid evaluation scope, except for the lowest quotation from Company B, the bidding quotations of the other five units were unusually close.
After checking the bidding documents, it is found that several bidding documents have the same mistakes:
1. Except for Company B, Company A, Company Q, Company H, Company D and Company W all said that "the lower part is massive C25 concrete", but there are the same mistakes. The name of the project provided in the bill of quantities of the tender document is also "C25 concrete with lower quality";
2. In the time (shift) table of bidders of Q company and H company, the unit price of AC welding machine (25KVA) is 14.35 yuan/set (hour), but the error in the calculation table of C30 portal crane concrete unit price of the two companies is 14.50 yuan at the same time. Both units have the same error.
3. When expressing the unit price of C20 concrete with a thickness of 15CM, except for Company B, the concrete strength grades of five other companies, namely Company A, Company Q, Company H, Company D and Company W, were mistakenly recorded as C25.
Five units suspected of colluding in bidding were inquired about the preparation of bidding documents and the bidding situation, and the inquiry records were made, and a hearing was held as required. Well, all five companies stressed that the bidding documents were compiled independently, denied collusion, and said that the abnormal consistency of bidding documents and the difference in quotation regularity could not be explained.
According to the first and fourth paragraphs of Article 40 of the Bidding Regulations: "(1) The bidding documents of different bidders are compiled by the same unit or individual; (4) The bidding documents of different bidders are unusually consistent or the bidding quotations are regularly different. After hard work, strict verification, strict hearing procedures and administrative punishment procedures, we found that five other companies (A, D, H, Q, W) colluded in bidding, and at the same time, the five units involved in collusive bidding were punished accordingly.
